perf mem: Fix -C option behavior for perf mem record

The -C/--cpu option was maily for report but it also affected record as
it ate the option.  So users needed to use "--" after perf mem record to
pass the info to the perf record properly.

Check if this option is set for record, and pass it to the actual perf
record.

Before)
  $ sudo perf --debug perf-event-open mem record -C 0 2>&1 | grep -a sys_perf_event_open
  ...
  sys_perf_event_open: pid -1  cpu 0  group_fd -1  flags 0x8 = 4
  sys_perf_event_open: pid -1  cpu 1  group_fd -1  flags 0x8 = 5
  sys_perf_event_open: pid -1  cpu 2  group_fd -1  flags 0x8 = 6
  sys_perf_event_open: pid -1  cpu 3  group_fd -1  flags 0x8 = 7
  sys_perf_event_open: pid -1  cpu 0  group_fd -1  flags 0x8 = 8
  sys_perf_event_open: pid -1  cpu 1  group_fd -1  flags 0x8 = 9
  sys_perf_event_open: pid -1  cpu 2  group_fd -1  flags 0x8 = 10
  sys_perf_event_open: pid -1  cpu 3  group_fd -1  flags 0x8 = 11
  ...

After)
  $ sudo perf --debug perf-event-open mem record -C 0 2>&1 | grep -a sys_perf_event_open
  ...
  sys_perf_event_open: pid -1  cpu 0  group_fd -1  flags 0x8 = 4
  sys_perf_event_open: pid -1  cpu 0  group_fd -1  flags 0x8 = 5
  sys_perf_event_open: pid -1  cpu 0  group_fd -1  flags 0x8 = 6
  sys_perf_event_open: pid -1  cpu 0  group_fd -1  flags 0x8 = 7
